Question

Add 10 to 5 times the difference of the
product of 9 and 15 and the sum of 65 and 35​

Answer 1

Answer:

Product of two number is 15, and we already know one number is 5. Say the other number is x

x * 5= 15

(x*5) / 5= 15/5 : Divide both side by 5 to cancel out the 5 on the left hand side

x = 3

Therefore the other number is 3. Hope this helped :)

Answer 2

Step-by-step explanation:

"Add 10 to 5 times the difference of the product of 9 and 15 and the sum of 65 and 35​"

· Sum of 65 and 35 = 65 + 35

· Product of 9 and 15 = 9 × 15

· Difference of product of 9 and 15 and the sum of 65 and 35. Two cases are possible:-

i) (65 + 35) - (9 × 15)

ii) (9 × 15) - (65 +35)

· 5 times the difference of... = Any of the two cases × 5

· Add 10 to 5 times the... = 10 + (Any of the two cases × 5)

Case 1:-

10 + [5{(65 + 35) - (9 × 15)}]

= 10 + {5(100 - 135)}

= 10 + {5 × (-35)}

= 10 + (-175)

= 10 - 175

= - 165

Case 2:-

10 + [5{(9 × 15) - (65 +35)}]

= 10 + {5(135 - 100)}

= 10 + 175

= 185

So when (65 + 35) - (9 × 15), answer is - 165, and when (9 × 15) - (65 +35), answer is 185. Hope it helps!
